  CASE WITH MIRROR AND ITS PROTECTIVE PART

FIELD OF THE INVENTION

  The invention relates to the field of housings intended to contain products

  cosmetics or beauty products, typically makeup powders.

STATE OF THE ART

  In general, the housings typically comprise a hollow lid provided with an inner mirror, a recessed bottom provided with a grid or intermediate support of at least one cup intended to receive the said cosmetic product, a hinge, constituting the connecting member between said cover and said bottom, allowing the articulation of said cover and the opening of said housing, - a clasp or any means for locking and unlocking said cover relative to said bottom, so as to ensure the opening and closing said housing, a clasp being

typically push button.

  We know very many modalities of cases, modalities which can relate to a

  or more of the constituents of the housing.

  Thus, with regard to the patents in the name of the applicant, there may be mentioned - the patent FR 2 661 080 which describes a make-up case with a small clasp, - the patent FR 2 701 365 which describes a transformable make-up case - Patent FR 2,725,958 which relates to a close-coupled housing with assistance to the opening, - Patent FR 2,737,192 which describes a housing with pivoting lid provided with a hinge with flexible legs, - Patent FR 2 755 352 which describes a box with assisted opening, - the patent FR 2 755 353 which describes a casing with unlocking push and pre-opening, - the patent FR 2 756 155 which describes a casing, the type comprising a bottom, a

  intermediate tray and a lid with an inner mirror.

  After conditioning the cosmetic products, generally in the form of solid products, or optionally non-fluid pastes with very high viscosity, the casings may incorporate a means of application of said cosmetic products, typically a puff in the most frequent case o said cosmetic product is a makeup powder, houpette having the general shape of the housing and taking place inside the housing between said mirror and said cup filled with said cosmetic product. Said puff is generally of flexible and fibrous material, which allows to take a little powder

  from the bucket and then apply it on the face.

PROBLEM

  A problem frequently observed by the users of said housings is that of the more or less rapid soiling of said mirror. Indeed, although, at the beginning of its use, said houpette has a side "powder" and a side "mirror" distinct, it has been observed, in use, a gradual soiling of the mirror, due, among other things,

  in contact with said hoopette with said mirror.

  The Applicant has therefore undertaken research to resolve this problem.

DESCRIPTION OF THE INVENTION

  According to the invention, the box intended for the packaging of cosmetic products comprises a hollow lid provided with an inner mirror and a first hinge portion, a hollow bottom comprising at least one cup intended to receive said cosmetic products and provided with a second hinge portion, a hinge, formed by cooperation of said first and second hinge portions, oriented in a direction or axis Y'-Y, allowing the relative rotation of said lid relative to said bottom about said axis, at an angle Oxz dihedral edge Y'-Y, and thus the opening and closing of said housing, a clasp or any means of locking and unlocking said cover relative to said bottom, and optionally an applicator of said cosmetic product, and is characterized in that it comprises a) a protective flap of said mirror by interposition between said mirror and said cosmetic product, secured to said housing by an anchoring means e, typically so that it can not be separated from said housing, b) means for said flap to be actuable by said rotation of said lid, and can be moved away from said mirror, and thus, said flap being placed in front of said mirror, in the so-called "mirror protection" position when said casing is closed, - it deviates laterally from the mirror in the so-called "use of the mirror" position when said cover is rotated with respect to the axis of said hinge for opening said casing, the dihedral angle Oxz then increasing to its maximum value OXZm, typically between 100 and 160, and then resuming its so-called "mirror protection" position when said cover is subjected in a reverse rotation to close said housing, the dihedral angle Oxz decreasing

  up to its minimum value Oxz ,, typically equal to 0.

  The invention will be better understood by means of the figures whose description follows and which

all illustrate the invention.

  The result of the invention appears clearly in FIGS. 1, 2 and 3, the means of

  the invention and the structure of its main elements being described in the other figures.

DESCRIPTION OF THE FIGURES

  FIGS. 1 and 2 are diagrammatic front perspective views of the housing (1) comprising a cover (2) carrying an internal mirror (21) articulated along the Y'-Y axis by means of a hinge (6) - not visible in the figure - and a bottom (3) containing a clip-on grille (3 1). A plane P of symmetry - represented by a dashed line - passes through the middle of the hinge (6) and is perpendicular to the axis Y'-Y, axis of rotation of the

hinge (6).

  In Figure 1, the lid is partially open, and the angle 2.cO. is close to zero, the

  mirror is thus fully protected.

  In Figure 2, the lid is fully open, and it is observed that the two half-shutters

  (5) are separated by an angle 2.cO and thus reveal the mirror (21) for the most part.

  FIGS. 3a to 3c are sectional views along the plane P of the box (1) according to the invention comprising two half-flaps (5), the lid (2), having an inner mirror (21), being closed in Figure 3a, with an angle Oxz equal to 0, slightly open in Figure 3b, with

  an angle Oxz close to 15, open with an angle Oxz at 50 in Figure 3c. Half

  flaps (5) have not been rotated in Figures 3a and 3b and have been rotated by one

  angle equal to Oxz '> 0 in Figure 3c.

  The housing (1) comprises a hinge (6) with axis of rotation (60) in the Y'-Y direction, a clasp (7), and a gode (33) containing said cosmetic product (35) topped with a

  means of application, a houpette (34).

  The horizontal plane passing through the hinge (6) is represented by the line X. The mean plane of the lid (2) is considered as the plane containing the mirror (21) and is represented by the line Z. The average plane of the half flaps (5) is represented by the right

Z '.

  Oxz 'angle of the half-flaps (5) is 0 in Figure 3a and 3b and is about 40 at the

Figure 3c.

  FIGS. 4a and 4b are graphs which illustrate the one-to-one relationship between the displacement of the half-shutters (5), in ordinate, and the opening angle Oxz of the lid

worn on the abscissa.

  The displacement of the half-flaps (5) comprises, on the one hand the angle of rotation Oxz 'in Figure 4b, and on the other hand, in Figure 4a, the angle ct of lateral spacing or opening angular (relative to the plane P), so that the angular aperture between the half-flaps (5) is 2. Oc To avoid the superposition of curves, the opening of the housing (steps I and II) has been represented on the left part of FIGS. 4a and 4b, and the closure of the box (steps III and IV) has been illustrated on the right part of FIGS. 4a and 4b, and the axes

  Oxz abscissa have been oriented toward each other to improve the clarity of the graph.

  It may be noted that, during the opening of the housing, the half-shutters start to depart only during step II (FIG. 4a), after a rotation of an Oxz angle of about 80 during step I The angle Oxz 'inclination of the half-flaps being about 60 (Figure 4b) at the end of step I. Similarly, conversely, the closure of the housing first comprises an essential phase III of folding half -volets, followed by a final phase IV rotation of

folded half-shutters.

  FIG. 5 is an exploded perspective view of the lid (2) illustrating the first hinge portion (20) integral with said lid, which is in this case a male hinge element (61), comprising a central bore (610), and a succession, according to the axis

  Y'-Y, a recessed portion (612), a solid portion (611) and a recessed portion (612).

  Figures 7, 9 and 10a to 10c will complete the illustration of the male hinge member (61). Figure 6 is a bottom view of said ring-shaped clapper (31). The grid (31) comprises a clasp or closure element (7), four clipping hooks (310), shown in more detail in FIG. 11, and, opposite the clasp (7), the second hinge portion ( 30), which is in this case a female hinge element (62) comprising a cavity (622) limited by two flanges (620) each carrying a central bore (621) not visible in the figure but represented by the Y axis '-Y. In the inner wall of said cavity (622) are formed two symmetrical grooves (9) comprising a portion (90) substantially parallel to the plane P followed by a portion (91) deviating from the plane P. As will be explained next, each groove (9) guides a lug (8) of a half-flap (5) and thus directs the half-flap (5). The displacement of said pin (8) in the first part of the groove (90) substantially corresponds to the rotation of the half-flaps (phases I and IV in FIGS. 4a and 4b), while at the displacement of said pin (8) in the second part of the groove (91) substantially corresponds to the spacing of the half-shutters

  (phase II) and their folding (phase III) (see Figures 4a and 4b).

  FIG. 7 is a sectional view similar to FIGS. 3a to 3c of a housing illustrating the hinge (6) with axis (60) comprising - the first hinge portion (20), the male element (61) of the hinge ( 6) forming part of the lid (2), - the second hinge portion (30), female element (62) of the hinge (6) forming part of the grid (31) clip-on bottom (3), - the legs of anchoring (50) the two half-flaps (5), shaped "5", comprising a shoulder (51) whose end is referenced (510), and a connecting element (52) can also play a role 8 is a perspective view of a half-flap (5) used in the examples of FIG.

embodiment of the invention.

  Figure 8a shows a partial view of a pair of half-shutters with complementary surface. FIG. 9 is a diagrammatic section of the hinge (6) with axis (60), in a horizontal plane, making it possible to understand its assembly: starting from the male element (61), of length L, comprising a solid part (611) with, on either side, a recessed portion (612), the shoulders (50) of the tabs (51) of the two half-flaps (5) are placed on the said recessed portions (612), the lugs (8) being oriented outwards, - this set is placed in the cavity (622), so that the lugs (8) penetrate into the grooves (9) on the surface of said cavity, that the central bores (610, 621) of the male and female portions are aligned,

  - The whole is secured by sliding the pin (63) in these central bores.

  the base (3) is then fixed by clipping, which makes it possible to completely mask the

hinge (6).

  Figures 10a to 10c are sectional views of the male member (61) in a plane

perpendicular to the axis (60) Y'-Y.

  FIG. 10a shows the recessed portion (612) of the male element (61), the recess (6120), of thickness "e", extending over an angle f of the order of 270, its edges

  extremes forming abutments A (613) and B (614).

  Figure 10Ob shows the solid portion (611) of the male member (61). Figure 10c is similar to Figure 10Ia, but illustrates the cooperation of the shoulder (41,51) with the male member (61). The spacing between the respective abutments of the shoulder - end (410) and segment (42) - and of the male element (61) - stops A and B, leads, for said corresponding shoulder or flap (4,5), at an angular clearance equivalent to a free rotation of angle y in FIG. 10Oc, the segment (42) being assumed

  resting against the abutment (614) B of the male element.

  FIG. 11 represents a schematic section of the assembly by clipping of the bottom (3)

  provided with clipping edges (32) and the grid (31) provided with clipping hooks (310).

  FIG. 12 represents, in section similar to that of FIG. 7, a housing modality according to the invention, in which the bottom (3) comprises an orifice (36)), the grid (31) comprises lateral ribs of attachment (311), the bucket (33) comprises a cover (332), a hinge (330) and an opening tongue (331), a bottom of reduced diameter (332) cooperating with said orifice (36), the wall bucket side including a groove under tongue (324) and a hinged obviously (333), so that said bucket can both be oriented, by unclipping and reclipsing, with the tongue, at choice, or on the right , to the left, and be open without being unclipped

  and disengaged from said grid (31).

  DETAILED DESCRIPTION OF THE INVENTION

  In the housing (1) according to the invention, said anchoring means may be an anchoring tab (40, 50) which cooperates with said first (20) and second (30) portions of said hinge (6), so that said flap (4,5) is actuable by said rotation of the cover (2), and that the angular position of said flap corresponding to said anchor tab (40,50), position defined by a dihedral angle Oxz 'edge Y'-Y, a predetermined function, and typically one-to-one, the value of the Oxz dihedral angle Y'-Y edge of the lid (2), the dihedral angle Oxz being typically at least equal to

the dihedral angle Oxz '.

  Thus, according to the invention, said flap-is both secured to said hinge and moved by

  the relative movement of the cover and the bottom (or its gate) at the hinge.

  An example of this one-to-one function linking the Oxz 'angle to the Oxz angle is shown in FIG.

Figure 4b.

  The respective rotation of the flap (4,5) and the lid is illustrated in FIGS. 3a to 3c

  According to one embodiment of the invention, said flap comprises two half-flaps (5), or half

  flaps, each half-flap (5) being provided with its own anchoring tab (50), the half

  flaps being symmetrical or not with respect to a plane P perpendicular to the axis Y'-Y passing through said hinge (6), but having complementary surfaces so as to ensure the protection of said mirror, as illustrated in FIG. 8a, in covering

  substantially most, if not all, of its surface.

  According to the invention, the cooperation of said anchoring tab (40,50) of said flap (4) or of each half-shutter (5) with said hinge (6) makes it possible, when said case (1) is opened firstly, a rotational movement of said flap (4) or half-flap (5) about said axis (60) of direction Y'-Y, rotation defined by a dihedral angle Oz'x, typically at least equal to 45 during which said flap (4) or the half-flaps (5) is in the so-called protective position of the mirror ",

  - then a movement comprising a lateral spacing of said flap (4) or both half

  flaps (5) by rotation of said anchoring means relative to said hinge taken as a center of rotation, spacing defined by the lateral angular deviation o, that is to say the inclination of the center line of said flap or the central edge of each of the half-shutters with respect to the plane P, the angular difference a. being sufficient, and typically greater than 30 (an angular deviation of 2.0 = 60 for a pair of half-flaps) for the mirror

  (21) is accessible and discovered, at least for the most part, that part (4) or half

  flaps (5) thus being in a position called "use of the mirror", and a reverse movement

  occurring during closure of said housing (1).

  Figures 1 and 2 illustrate the successive phases of rotation of the half-flaps (5) to the

  Figure 1, and their spacing in Figure 2.

  Preferably, said lateral angular deviation a is a predetermined, and typically one-to-one, function of the value of the dihedral angle Ozx formed by the cover when

  opening or closing said lid.

  This is clearly illustrated by FIGS. 4a and 4b where the evolution of the angles of rotation Oxz 'and of spacing ca as a function of the angle Oxz can be observed graphically.

  opening of the lid, and this, both at the opening and closing of the lid.

  This embodiment corresponds to the maximum security with regard to the protection of the mirror, since, the spacing of the half-shutters takes place only when the mirror is at a relatively large angular distance from the cosmetic product (35) contained in the bucket (33) or the puff (34), current application means of said

cosmetic product.

  However, the invention also includes housings, probably a little less powerful, in which the shutter or the half-shutters can begin to deviate shortly after the

beginning of the lid opening.

  It may be advantageous for said hollow bottom (3) to comprise a grid or intermediate support (31) of said bucket (33) intended to receive said cosmetic product (35), said grid (31) being integral with said bottom (3), typically by clipping or welding, and comprising said second hinge portion (30) for cooperating with said

  first hinge portion (20) of said lid (1).

  An interest of this type of configuration, illustrated in most of the figures, is to mask the hinge (6), as illustrated for example in FIGS. 7 and 9, and in a general way, to separate the technical functions from the decorative functions, the former being assigned to the grid or support of the bucket, the seconds at the bottom, which can be

richly decorated.

  However, this is a non-mandatory modality, the functions of the invention being

be obtained without a grid.

  Similarly, according to the invention, said hollow cover (2) may comprise a grid or support (23) of said mirror (21), said grid (23) being integral with the cover (2), typically by clipping or by welding, and including said first hinge portion (20) for cooperating with said second hinge portion (30) of the bottom

(3) or said grid (31).

  This modality has not been represented by a figure, but it is easy to understand

  the light of what has been said about the grid (31) clipable in the bottom (3).

  According to an advantageous embodiment of the invention, the housing has the combination of the following elements: a) said hinge (6) is formed by the cooperation of a male element (61) constituted by said first (20) or by said second (30) hinge portion, of length L in the Y'-Y direction, typically between 10 and 20 mm, provided with a first central bore (610), and a female element (62), constituted respectively by said second (30) or said first (20) hinge portion forming a cavity (622) provided with two opposite flanges (620) spaced apart by at least the length L, each of the two flanges (620) being provided with a second central bore (621), the first (20) and second (30) hinge portions cooperating by fitting the male and female elements, so that the bores (610, 621) of the male and female elements are aligned according to the axis (60) Y'-Y direction and an ankle (63) for blocking said cha rnière (6) can be introduced into said bores (610,621), as shown in Figure 9, b) said male element (61) comprises, along the axis Y'-Y, a solid portion (611) and at least one recessed portion (612), said recessed portion (612) comprising a partial peripheral recess (6120), of thickness "e" in the radial direction with respect to the Y'-Y axis, typically between 1 and 2 mm, of width, along the axis Y'-Y, typically between L / 4 and L / 3, and extending along an arc of angle of angle f3, typically between 180 and 300, one end of said obvious forming a stop A Il (613) for the rotation of said inking lug (40, 50), as illustrated in FIGS. 10a to Oc, c) said anchoring lug (40, 50) comprises a shoulder (41, 51) forming an arc whose width and curvature are chosen so that said shoulder (41,51) can cooperate with said recessed portion (612) and substantially fill said recess (6120) , said shoulder (41,51) extending circumferentially at an angle of less than 180, typically between 120 and 175, with an end A '(410,510) abutting against the corresponding end A (613) of said recess ( 6120), as illustrated in FIGS. 10a to 01c, d) said anchoring tab has freedom of rotation with respect to the Y'-Y axis, limited by said cover (2) itself and by said stopper A ( 613), freedom equivalent to an angle y, typically between 10 and 50 and chosen as a function of the depth (25) of said cover (2), so that, on the one hand, during the opening of the cover ( 2), the end A '(410,510) of said shoulder (41,51) abuts against the end A (613) of said recess (6120) and that said flap (4) or half-flaps (5) are of this fact is offset by an angle y relative to the lid (2) during the opening of the lid, so as to make possible a lateral angular deviation ao flap (4) or half-flaps (5) without this lateral movement is hindered or prevented by the flange (24) of said cover (2) height (25) (see Figure 7), and so that whereas, on the other hand, during the closure of the lid, the shutter (4) or the half-shutters (5) are driven by

  rotation either directly by pressing the cover (2) against the flap (4) or half

  flaps (5), or possibly by the support of a second stop B (614), at the other end of said recess (6120), against a corresponding second stop B '(42,52)

  of said tab (40,50), as illustrated in Figure 10c.

  In the case of a housing having a very flat cover, the angular displacement in rotation y between the shutter and the cover could be very small, since it would be sufficient to be offset by a few degrees so that this shutter can move laterally without hit the edge of the lid. In the figures, there is illustrated more particularly the case where said flap comprising two half-flaps (5), each being provided with an anchoring tab (50), and o said male element (61) comprises a solid part ( 611) separating two recessed portions (612), each having a peripheral recess (6120), said shoulder (51) of each

  anchoring tab (50) cooperating with a peripheral recess (6120).

  According to one embodiment of the invention, the means for spacing said flap (4) or said half-flaps (5) laterally from the mirror (21) during the opening of the lid (2) so that it is in said position " use of the mirror ", then to resume its so-called" mirror protection "position when closing the lid (2), can be constituted by the cooperation of a lug (8) integral with said lug ( 40) or each of the tabs (50), with a groove (9) guiding said pin (8) and imposing it, as well as said corresponding tab (40,50) and flap (4) or half-shutters (5) corresponding, a predetermined displacement, and in particular a predetermined lateral displacement, said

  groove (9) being formed on the inner wall of said cavity (622).

  This is illustrated in Figures 7, 9, the grooves (9) also appearing in Figure 6.

  According to another embodiment of the invention, "inverse" of the preceding one, the means for moving said flap (4) or each of the half-flaps (5) laterally away from the mirror (21) when opening the lid (2) , and thus put it in position called "use of the mirror", then, when closing the lid (2), to return said flap or half-flap to its initial position called "mirror protection", can be formed by the cooperation of at least one lug (8) placed on the inner wall of said cavity (622), and a groove (9) formed on the lug (40) of said flap (4) or on each of tabs (50) of the half-flaps (5), so that said lug (8) imposes on said groove (9), as well as said corresponding lug (40,50) and shutter or half-flap corresponding (4,5), one

  predetermined displacement, and in particular a predetermined lateral displacement.

  This modality has not been illustrated by a figure but can easily be deduced from

  figures relating to the previous modality.

  According to the invention, it has been found advantageous that said cavity (622) of said hinge (6) is provided with two flanges (620) separated by a length, greater than L, large enough to leave, on both sides other of said male element (61), a free space (64), typically of a few mm, so as to make possible - following the movement imposed on said shoulder by the rotation of the lid and taking into account the cooperation of said lug (8) and said groove (9) - a tilting around the end (615) of said

  male part along the axis (60), in the manner of a swivel movement.

  As illustrated in FIG. 8, said anchoring tab (40, 50) may have, in section along said plane P, the shape of a "5", the upper right end of the "5" being prolonged

  by said flap (4) or half-flap (5).

  According to the figures, said hinge (6) can be formed by the cooperation of said male element (61) constituted by said first hinge portion (20) connected to the cover (2) or to said grid (23) secured to said cover ( 2), and said female element (62) constituted by said second hinge portion (30) bonded to the bottom (3) of the

  housing or grid (31) integral with the bottom (3) of the housing.

  But, conversely, said hinge (6) can also be formed by the cooperation of said female element (62) constituted by said first hinge portion (20) connected to the cover (2) or to said grid (23) integral with said cover ( 2), and said male element (61) constituted by said second hinge portion (30) bonded to the bottom (3) of the housing or

  to the grid (31) integral with the bottom (3) of the housing.

  The invention is not limited to the housings illustrated by figures and the use of a flap to protect said mirror. Said shutter (4) or the half-shutters (5) can themselves form a mirror, and / or form a support for small accessories

  necessary for the application of said cosmetic products.

  According to a particular embodiment of the invention, said bucket (33) may be a reversibly reversible clipping bucket in said housing, with a sealed cover (332) provided, for its opening, with a lateral hinge (330) and a tongue (331) diametrically opposed, said bucket (33) and its tongue (331) being oriented at + 1-90 relative to the axis formed by the hinge (6) and the clasp (7) of said housing (1) , so that the housing (1) and its bucket (33) are adapted, indifferently, to a

  use by a right-handed or left-handed person.

  This modality is illustrated in Figure 12.

  The invention is not limited to a particular form of housings. The outer shape of the housing may be arbitrary, and preferably chosen from the usual shapes of the housings, the sectional shape in the horizontal plane being round, square,

rectangular, oval or oblong.

  The section in a vertical plane can also be chosen from the usual forms

  0o round, square, rectangular, oval or oblong shape.

  The shape of the bucket is limited only by having to register in said boot.

  Another object of the invention is a method of manufacturing the casing in which a) supplying: a) a first housing part provided with said male hinge element (61), lid (2) or bottom (3) as appropriate , a2) the shutter (4) or the pair of half-shutters (5) provided with its / their tab (s) hanging

(40,50),

  a3) according to the case, a grid (31) clipping in said bottom ((3), or a grid (23) clipping in said cover (2), said grid, a second housing part, being provided with said hinge element female (62), a4) a locking pin (63) of said hinge (6), aS) a second housing part, respectively a bottom (3) or a cover (2) as appropriate, b) said orientation first portion of casing ai), so that we can put the shoulder (41) of the tab (40) or the shoulders (51) of the legs (50) on 1 '(the) obviously (s) ) (6120) of the male hinge element (61), typically in a gravity-stable manner, c) forming said hinge (6) and placing it above the assembly formed in b), said grid (31, 23) provided with said female hinge element (62) and said hinge (6) is locked by sliding said pin (63) into the previously aligned bores (610, 621) of each of the elements of the male hinge (61) and female (62), d) said bottom (3) or said cover (2) are respectively clipped on said grid (31, 23) as appropriate, so as to form a housing (1) whose hinge (6) and wherein said tab (s) (40,50) are invisible externally. In this process, the parts supplied under al, a2, a3 and a5 can be parts

  molded, typically plastic, metallized surface or not.

EXEMPLARY EMBODIMENT

  All the figures correspond to the same housing (1) according to the invention.

  The process was carried out as described in the process according to the invention and the parts were manufactured

  molded plastics, the lid and the bottom having then been metallized.

  The main dimensions of this case are shown in figure 7 total outside diameter: 75.2 mm - diameter of the mirror: 50 mm - diameter of the houpette: 50 mm - height of the houpette: 7 mm - inside cup height: 7 mm - inside diameter of the bucket 50 mm - diameter of the orifice (36): 20 mm The structure of the cover (2) and the first hinge portion (20) appears at the

figure 5.

  The detailed structure of the grid (31) is given in FIG.

  The bottom (3) has the shape shown in Figure 7. It comprises four clipping edges (32) as schematically in Figure 11, angularly spaced about 90, so

  to cooperate with the clipping hooks (310) shown in Figure 6.

  The half-flaps (5) are those represented in FIG. 8.

  The assembly of these elements has been performed without any difficulty in the manner already mentioned. It has been found that, during the opening and closing tests of the casing carried out by persons representing the users of said casings, the movement of the half-shutters has been found quite regular, with no dead point or blockage, so that the the user does not have to touch the half-shutters that move apart or replace themselves automatically

  by the only movement of opening and closing the lid.

ADVANTAGES OF THE INVENTION

  In its field of application, which is that of cosmetics, the invention is of great interest in two main ways - on the one hand it solves the specific problem of the protection of the mirror, an unresolved problem to date in this means that no case of the state of the art has described a way to protect the mirror, except by requiring the user to take measures

  specificities that go beyond the natural gestures of opening and closing the case.

  Thus, it is clear that, without the user having to intervene in anything, the mirror with a housing according to the invention will be protected from contact with the houpette or any other type of applicator and will remain clean, on the other hand, such a remarkable result has been obtained with the most limited number of pieces (the only piece in addition to the standard case being the half-flaps themselves), these parts being also easily moldable, and with a process of assembly of great simplicity, thanks to the particular cooperation between

  the legs of the shutters or half-shutters and the elements of the hinge.

  All this makes the invention easily to industrialize.

  In addition, this invention has the advantage of offering a high degree of miniaturization and "discretion", the mechanism being finally "hidden" in the hinge itself, this

  which is of the greatest interest for packaging used in cosmetology.

  Finally, this invention has a large scope insofar as it discloses a general means for transforming a simple rotational movement of a workpiece into a predetermined movement of another workpiece, which can find its application in the field of packaging endowed hinged lids other than casings, in particular to fulfill new functions useful to the ultimate consumer, and thus

  create a new offer of products derived from known products.
